Claims20
An absorbent composite comprising:
- a plurality of superabsorbent particles;
- wherein the plurality of superabsorbent particles are microembossed with an average major dimension in the range of from about 100 µm to about 1000 µm.
A method of manufacturing an absorbent composite, the method comprising:
- contacting a plurality of superabsorbent particles with an embossing roller comprising a plurality of pins;
- and
- embossing the plurality of superabsorbent particles with the embossing roller at a pressure in the range from about 125 psi to about 1000 psi;
- wherein the plurality of superabsorbent particles are microembossed with an average major dimension in the range of from about 100 µm to about 1000 µm.
